Dredger's Insight

Whenever one or more artifact and/or creature cards leave your graveyard, you gain 1 life.
When this enchantment enters, mill four cards.
You may put an artifact, creature, or land card from among the milled cards into your hand.
When a saporling dies, it will be eaten by another, which will then die, and so on, so technically every saporling is made of every saporling.
